  • x / y = x per y

    PR = PS + SR
    PR = PS + 3

    ST / RQ = PS / PR
    10 / 15 = PS / (PS + 3)
    15 × PS = 10 × (PS + 3)
    15PS = 10PS + 30
    15PS - 10PS = 30
    5PS = 30
    PS = 6 cm

    PQ = PT + TQ
    PQ = 6 + TQ

    ST / RQ = PT / PQ
    10 / 15 = 6 / (6 + TQ)
    6 × 15 = 10 × (6 + TQ)
    90 = 60 + 10TQ
    90 - 60 = 10TQ
    30 = 10TQ
    TQ = 3 cm

    PS + TQ = 6 cm + 3 cm
    = 9 cm (tidak ada pilihan jawaban)
